Home » Structure » Post Tension Slab. The post tension slab is a combination of traditional slab reinforcement and additional high-strength steel tendons, which are subject to stress after the setting of concrete. Generally pre-cast elements where the strand or bar is stressed before the concrete being poured over it no ducts used. A post tension slab generally refers to a section of cured concrete, which has tensile forces introduced into the slab after the concrete has set. These internal forces are provided by tensioning the high-strength steel that occurs before or after the concrete is positioned. Thin sheet metal pipes with the claw coupling or welded overlapped seams of 5 and 6 meters length are offered.
Guido Altersberger. This post is about how to define post-tensioned slabs within Revit The definition of Tendons in Revit is done by a simplified method.
Abstract: Post-Tensioning allows almost any shape of structure to be constructed, while reducing environmental impacts, construction time, materials and costs. Since the PT technology has advanced significantly particularly in the field of performance, quality assurance and durability as well as corrosion protection. Parameters varied were, amount of reinforcement, and location of reinforcement. Readings from strain gages on the rebar were used to investigate the impact of PT slab on the service stresses. Crack width measurements were made at regular intervals and compared to strain readings.
